Build a daily German and EU public-tender alert in Python with the free TED Search API

#api #python #opendata #tutorial

TED, Tenders Electronic Daily, is the Supplement to the Official Journal of the European Union. The EU Publications Office runs it, and public buyers from across the EU publish their procurement notices there in a common format. In the first week of November 2026 it carried notices from a Baden-Württemberg state ministry, Bavarian universities, a Dutch province and an Austrian state government.

TED has its own search page and alerts. A script you control lets you combine filters the way you want, keep the results in a spreadsheet and plug them into whatever comes next. TED's Search API makes that easy: it is a single HTTPS endpoint, and you don't need a key or an account.

The script in this tutorial:

  1. builds one TED query for buyer countries, a publication-date window, open calls for competition and CPV codes,
  2. pages through every match, 250 notices per request,
  3. picks a readable title and buyer name out of 24 languages,
  4. works out the next deadline and drops notices that close too soon,
  5. filters by keyword without the usual false hits,
  6. remembers what it has already reported, writes a CSV and an email-ready text file, and runs every weekday.

Dependencies: Python 3.9+ (tested on 3.13) and requests. The full script is at the end. All figures below come from live runs on 5 November 2026.

One request

The endpoint is POST https://api.ted.europa.eu/v3/notices/search. The API documentation says the Search API "does not require a key". You send a JSON body with a query in TED's expert-search syntax and the list of fields you want back:

import requests

body = {
    "query": "buyer-country IN (DEU) AND publication-date=20261104 AND form-type IN (competition)",
    "fields": ["publication-number", "notice-title", "buyer-name", "deadline-receipt-tender-date-lot"],
    "limit": 3,
    "paginationMode": "ITERATION",
}
r = requests.post("https://api.ted.europa.eu/v3/notices/search", json=body, timeout=60)
data = r.json()
print(data["totalNoticeCount"], len(data["notices"]))
Enter fullscreen mode Exit fullscreen mode

On 5 November that query reported 343 calls for competition from German buyers published on 4 November. A trimmed result looks like this:

{
  "publication-number": "763834-2026",
  "notice-title": {"deu": "Deutschland – Einbau von Fenstern – Generalmodernisierung Hl. Geist Spital Landshut: ...",
                   "eng": "Germany – Installation of windows – Generalmodernisierung Hl. Geist Spital Landshut: ...", "...": "..."},
  "deadline-receipt-tender-date-lot": ["2026-12-08+01:00"],
  "links": {"html": {"ENG": "https://ted.europa.eu/en/notice/-/detail/763834-2026", "...": "..."}, "...": "..."}
}
Enter fullscreen mode Exit fullscreen mode

Three things to notice. Text fields come back as a dictionary keyed by three-letter language code. Dates carry a UTC offset but no time. And every notice gets a links block with HTML, PDF and XML URLs in every official language, whether you asked for it or not.

Step 1: let the server do the filtering

The expert-search syntax combines field operator value clauses with AND/OR. My query builder:

def build_query(countries, day_from, day_to, cpv):
    parts = [
        f"buyer-country IN ({' '.join(countries)})",
        f"publication-date>={day_from:%Y%m%d}",
        f"publication-date<={day_to:%Y%m%d}",
        "form-type IN (competition)",
    ]
    if cpv:
        parts.append(f"classification-cpv IN ({' '.join(cpv)})")
    return " AND ".join(parts)
Enter fullscreen mode Exit fullscreen mode

With the defaults (Germany, IT services and software, the last three days), this produces:

buyer-country IN (DEU) AND publication-date>=20261103 AND publication-date<=20261105
AND form-type IN (competition) AND classification-cpv IN (72000000 48000000)
Enter fullscreen mode Exit fullscreen mode
  • Countries are ISO 3166-1 alpha-3 codes: DEU, AUT, NLD. A wrong code fails loudly. XXX returns HTTP 400 with "Value 'XXX' is not supported for search field 'buyer-country' in expert search", which the script prints and stops on.
  • form-type IN (competition) keeps calls for competition, the notices you can still bid on. Without it you also get contract awards (result), contract modifications, prior information notices and more. For German buyers over 3–5 November, 1,022 of 2,038 notices were calls for competition, 819 were results and 166 were contract modifications.
  • CPV (Common Procurement Vocabulary) codes classify what is being bought. The documentation says CPV search is hierarchical, so 72000000 (IT services) also matches its sub-codes. That matters in practice. Of the 51 notices in my default run, only 22 list 72000000 or 48000000 themselves. The other 29 matched only through narrower codes such as 72253200 (systems support) or 72212331 (business intelligence software development). Matching exact codes on the client would have missed more than half of them.

The hierarchy works both ways. CPV division 48 is "software package and information systems", and it also contains 48820000 Servers. So "Rack-Server inkl. Service" turned up in a software alert. If that's noise for you, use narrower codes.

Step 2: page through everything

The API returns at most 250 notices per page. It has two paging modes (limits documented here). Page-number mode stops at 15,000 notices per query. Iteration mode has no total limit: each response carries an iterationNextToken, which you send back to get the next page.

def fetch_notices(query, max_pages):
    body = {"query": query, "fields": FIELDS, "limit": 250,
            "scope": "ALL", "paginationMode": "ITERATION"}
    notices, total = [], 0
    for page in range(1, max_pages + 1):
        data = post_with_retry(session, body)
        batch = data.get("notices", [])
        total = data.get("totalNoticeCount", total)
        notices.extend(batch)
        token = data.get("iterationNextToken")
        if not batch or not token or len(notices) >= total:
            break
        body["iterationNextToken"] = token
        time.sleep(PAUSE_SECONDS)
    return notices, total
Enter fullscreen mode Exit fullscreen mode

A daily alert rarely needs more than one page. My default run found 62 notices in a single request. To test the loop, I dropped the CPV filter: three days of German calls for competition across all sectors came to 1,022 notices, fetched in five requests (4 × 250 + 22).

TED's Publications Office has published fair-use figures in its reusers' Q&A, including "700 requests in the last minute" for HTTP requests. This script is nowhere near that. Still, it sends a descriptive User-Agent, waits a second between pages and backs off on HTTP 429 and 5xx.

Step 3: ask only for what you need

The fields list decides what you get back. Mine is short and deliberately leaves out contact data:

FIELDS = [
    "publication-number", "publication-date", "notice-title", "buyer-name",
    "buyer-country", "classification-cpv", "place-of-performance",
    "deadline-receipt-tender-date-lot",    # open procedures: deadline for tenders
    "deadline-receipt-request-date-lot",   # two-stage procedures: deadline for requests to participate
    "notice-type", "procedure-type",
]
Enter fullscreen mode Exit fullscreen mode

The data-protection section of TED's legal notice says contract notices can include a contact person and office phone number. An alert doesn't need any of that: the notice link leads to the full official text. If you never request those fields, you never store them. (The documentation also caps a page at 10,000 fields in total, so a short list keeps 250 notices per page within that cap.)

For multilingual fields, a small helper tries your preferred languages in order and then falls back to whatever the notice has:

def pick_lang(value, prefer):
    if not value:
        return ""
    if isinstance(value, str):
        return value
    if isinstance(value, list):
        return str(value[0]) if value else ""
    for lang in prefer + list(value.keys()):
        v = value.get(lang)
        if v:
            return v[0] if isinstance(v, list) else str(v)
    return ""
Enter fullscreen mode Exit fullscreen mode

Buyer names usually exist only in the original language ({"deu": [...]}), but titles come in every official language. They also have a fixed shape: country – CPV label – the buyer's own title. Only the last part is the buyer's own wording, often still in German, even in the English version:

Germany – Data analysis services – Durchführung von Sentinel-Satellitendatenauswertungen im Rahmen des Flächenüberwachungssystems
Enter fullscreen mode Exit fullscreen mode

The script splits on the first two – separators and keeps both parts. The CPV label goes into its own column, and the buyer's title is what you read and search.

def split_title(full):
    parts = full.split(" – ", 2)
    return (parts[1], parts[2]) if len(parts) == 3 else ("", full)
Enter fullscreen mode Exit fullscreen mode

This turns out to matter for keyword search (Step 5). The country part can list several countries: one notice in my run, with buyers in three countries, started "Italy, Germany, France – ...". Because of maxsplit=2, that still splits correctly.

Step 4: the deadline that matters

Not every call for competition has a tender deadline. In an open procedure anyone can bid, so the notice has deadline-receipt-tender-date-lot. In a two-stage procedure, such as a negotiated procedure with a prior call, you first apply to take part, and the notice has deadline-receipt-request-date-lot instead. In my default run, 38 notices had the first kind and 13 the second. With only the tender field, those 13 would have had no deadline at all.

Both fields are lists, one entry per lot. The script takes the earliest date, records which kind it was and counts the days left:

deadline = earliest_deadline(n.get("deadline-receipt-tender-date-lot"))
kind = "tender"
if deadline is None:
    deadline = earliest_deadline(n.get("deadline-receipt-request-date-lot"))
    kind = "request to participate" if deadline else ""
Enter fullscreen mode Exit fullscreen mode

--min-days-left 10 (the default) drops anything closing within ten days, which is usually too little time to prepare a bid. That removed 11 of the 62 notices in the default run.

Two caveats. These fields hold a date only, so "days left" is approximate; check the exact time in the notice. And not every date is a real deadline. In the all-sector run, three notices for open-ended pharmaceutical rebate agreements gave 2099-12-31. Sort by deadline and they sink to the bottom, which is where they belong.

Step 5: keywords without false hits

CPV codes narrow the sector; keywords narrow the topic. The naive version, "ki" in title.lower(), goes wrong in two ways.

First, the CPV label. Every English title contains a phrase such as "IT services: consulting, software development, Internet and support", so a search for software matches every notice with that code. That's why the script matches only the buyer's own title and the buyer name.

Second, substrings. ki (the German abbreviation for AI, künstliche Intelligenz) is inside thousands of German words. In my first test it matched "Main-Kinzig-Kliniken". The script compiles keywords into one regular expression that matches whole words by default, with a trailing * meaning "word starts with":

def keyword_pattern(keywords):
    if not keywords:
        return None
    alts = [re.escape(k[:-1]) if k.endswith("*") else re.escape(k) + r"\b" for k in keywords]
    return re.compile(r"\b(?:" + "|".join(alts) + ")", re.IGNORECASE)
Enter fullscreen mode Exit fullscreen mode

ki now matches "KI-Plattform" (the hyphen is a word boundary) but not "Kinzig". daten* matches "Datenbank" and the "Daten-" in "Wissens-, Daten- und Austauschplattform". One limitation is specific to German: compounds put the interesting word at the end, so daten* won't find "Stammdaten". Add those words explicitly if you need them.

Here is a run for Germany, Austria and the Netherlands, IT services only, five days, with keywords daten*,data*,cloud*,ki,software*. TED returned 102 notices and 15 passed. Among them:

* Bereitstellung Data Science Entwicklungsplattform von Posit
  Charité - Universitätsmedizin Berlin (DEU) | tender deadline 2026-11-30 (25 days left)
  Software supply services (CPV 72268000)
  https://ted.europa.eu/en/notice/-/detail/758775-2026

* Business Intelligence (BI) Software
  Dachgesellschaft Bauvorhaben Hochschulmedizin Niedersachsen mbH (DBHN) (DEU) | request to participate deadline 2026-12-01 (26 days left)
  Business intelligence software development services (CPV 72212331 72212482)
  https://ted.europa.eu/en/notice/-/detail/757551-2026
Enter fullscreen mode Exit fullscreen mode

Step 6: report only what's new

A daily alert that repeats yesterday's notices gets ignored. The script keeps a small seen.json mapping publication numbers to the date they were first reported, and drops entries older than 120 days so the file stays small. The query window overlaps on purpose (--days 3), so a late or missed run doesn't lose anything, and the state file removes the repeats. Running the default query twice in a row gave 51 new notices, then 0 and "Nothing new since the last run." When nothing is new, no files are written.

Each run with new notices writes two files, stamped with date and time:

  • ted-alert-YYYY-MM-DD-HHMM.csv, saved as utf-8-sig so Excel shows "Universität" rather than mojibake,
  • ted-alert-YYYY-MM-DD-HHMM.txt, sorted by deadline and ending with the query, the source line and a reminder to check the official notice. It's ready to paste into an e-mail or a chat webhook.

The state is keyed on the publication number. TED also publishes change notices for corrections. My three-day German query had none to look at, so I haven't tested how they appear. If updates matter to you, check how they show up for your own query.

Schedule it

TED publishes once per business day, Monday to Friday. The API docs say new notices appear "no later than 09:00 CET" on their publication date. A weekday run at 10:17 Berlin time sees the day's edition.

With cron, on a machine set to Berlin time:

17 10 * * 1-5  cd $HOME/ted-alert && ./venv/bin/python ted_alert.py --countries DEU,AUT --cpv 72000000,48000000 --keywords "daten*,data*,cloud*,ki,software*" --days 3 --state seen.json --out-dir out >> alert.log 2>&1
Enter fullscreen mode Exit fullscreen mode

With GitHub Actions, the schedule can carry its own IANA time zone, and the docs advise against the top of the hour because scheduled jobs can be delayed or dropped under load:

on:
  schedule:
    - cron: "17 10 * * 1-5"
      timezone: "Europe/Berlin"
  workflow_dispatch: {}
jobs:
  alert:
    runs-on: ubuntu-latest
    timeout-minutes: 10
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-python@v5
        with:
          python-version: "3.12"
      - run: pip install -r requirements.txt
      - uses: actions/cache@v4
        with:
          path: seen.json
          key: ted-seen-${{ github.run_id }}
          restore-keys: ted-seen-
      - run: >
          python ted_alert.py --countries DEU,AUT --cpv 72000000,48000000
          --keywords "daten*,data*,cloud*,ki,software*" --days 3
          --state seen.json --out-dir out
      - uses: actions/upload-artifact@v4
        if: hashFiles('out/*') != ''
        with:
          name: ted-alert-${{ github.run_id }}
          path: out/
          retention-days: 30
Enter fullscreen mode Exit fullscreen mode

seen.json lives in the Actions cache. A cache can't be changed once saved, so every run saves a new one keyed by run ID, and restore-keys brings back the most recently created one. GitHub removes caches that haven't been accessed for seven days, so after a long break you'll see some repeats. In a public repository, scheduled workflows are switched off after 60 days without repository activity, which is one more reason to use a private one.

Terms and attribution

The TED legal notice says that, unless otherwise noted, "the procurement notices published in the Supplement to the Official Journal of the European Union can be freely reused, for commercial or non-commercial purposes". It implements that rule via the Commission Decision of 12 December 2011 (2011/833/EU) on reuse of Commission documents. Under Article 6(2) of that Decision, reuse conditions may include acknowledging the source, not distorting the original meaning, and the Commission's non-liability. The legal notice also says the SIMAP/TED logos may not be used without prior consent, that logos, trademarks and names sit outside the reuse policy, and that you may need to clear rights yourself if content shows identifiable private individuals. (The editorial content of the TED websites themselves is under CC BY 4.0; the notices follow the Decision above.)

Notices can contain personal data (contact names, professional emails, office phones). Do not scrape or republish those fields in bulk: request only the fields you need, and link to the official notice instead of copying contact details. That keeps a personal alert useful without turning it into a contact dump.

In practice: keep the source line ("TED – Tenders Electronic Daily, © European Union, https://ted.europa.eu") in anything you share, link to the official notice instead of rewriting it, and don't present your digest as an official EU product. The script's text output does all three.

Where to take it next

  • Add place-of-performance IN (DE3) (NUTS codes are hierarchical too, DE3 is Berlin) to watch one region.
  • Send the text file through SMTP or a chat webhook from the workflow.
  • Swap form-type IN (competition) for form-type IN (result) to watch who wins contracts in your sector instead.

  1. builds a TED expert-search query (buyer countries, publication-date window,
     open calls for competition only, optional CPV codes filtered server-side),
  2. pages through every match with ITERATION mode (250 notices per page max),
  3. keeps notices that match your keywords and still have enough days left,
  4. remembers what it already showed you (seen.json), so each run only reports new notices,
